The Hitachi Desktar 7K1000.C and WD Caviar Blue 1TB represent the latest evolution in mainstream 7,200 RPM hard disk drives. While not as fast as high performance 7,200/10,000 RPM models or SSDs, they are fast enough, reasonably quiet, and very affordable.http://www.silentpcreview.com/hitachi-wdblue-1tb
